Abstract
The invention discloses a novel optical cable compounded flat elevator cable. The flat elevator cable comprises a plurality of composite cables, a plurality of common cables and a flat sheath; the plurality of composite cables and the plurality of common cables are arranged on the same straight line regularly and are wrapped by the flat sheath; In each composite cable of the novel optical cable compounded flat elevator cable, novel optical cables and coaxial optical cables are compounded and the novel optical cables are positioned in gaps between adjacent coaxial cables, and cores in the novel optical cables are not needed to be strengthened; and the composite optical cables have a small outer diameter, the production process of the composite optical cables is simple and the composite optical cables are low in cost; and the flat elevator cable is low in production cost and long in service life.
Description
Technical field
The present invention relates to a kind of cable, the flat type elevator cable of the new composite optical cable that especially a kind of production cost is low, the life-span is long belongs to the cable technology field.
Background technology
At present, the electrical control insulated wire cores of flat type elevator trailing cable, insulation video monitoring cable adopts the various videos of transmission, data-signals such as coaxial cable, Shielded Twisted Pair.
And the structure of coaxial cable is solid insulation, shown in accompanying drawing 1, comprises cable cover(ing) 1, coaxial cable 2; Said coaxial cable has 2 or many, is wrapped up by cable cover(ing); Said coaxial cable 2 comprises core conductor 3, core insulator 4; Said core insulator 4 parcel core conductors 3; The coaxial cable of this structure causes technical indicators such as the decay, impedance of solid coaxial cable to be difficult to meet the requirements because of its reasons in structure, particularly poor anti jamming capability.
It is right to be compounded in the inner Shielded Twisted Pair of flat cable, although its structure and 3 types of lines, 4 types of lines are similar, the practical structure size is difficult to accomplish satisfy 3 types of transmission characteristic impedances such as line, decaying is difficult to meet the demands.This type shielding line is to being difficult to overcome the complicated electromagnetic interference in the elevator hoistways.Therefore, although be compounded in 3 types of lines, 5 types of lines in the flat type elevator cable, the distortionless specification requirement of transmission signals when also being difficult to meet the elevator operation.
Even with common optical fiber; Like tight tube fiber, loose tube fiber; Be compound in the flat type elevator cable, but, do not satisfy the requirement of flat type elevator cable long-time running owing to the reasons such as pulling force is little, the bending radius of bearing big, the glass light core fractures easily of bearing of tight tube fiber, loose tube fiber cable.The life-span of the flat type elevator cable of therefore, compound common optical fiber does not reach the test requirements document in elevator cable life-span.
Adopt common Optical Fiber Composite in flat type elevator cable, such optical fiber and common core stranding are compound, because optical fiber, the Tension Control that production equipment is required requires high, and is disconnected easily in the production process, so many shortcomings such as production cost height.
Summary of the invention
The present invention seeks to have proposed the flat type elevator cable of the new composite optical cable that a kind of production cost is low, the life-span is long for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of flat type elevator cable of new composite optical cable comprises composite cable, common cable, flat sheath; Said composite cable, common cable have many respectively, are arranged on straight line regularly, by flat sheath parcel.
Preferably, said composite cable comprises coaxial cable, sheath; Said coaxial cable has 2 or many; Be provided with novel optical cable in the space between the said adjacent coaxial cable; Said sheath wraps all coaxial cables, novel optical cable; Said coaxial cable comprises core conductor, core insulator; Said core insulator parcel core conductor; Said novel optical cable comprises fibre core, interior tegillum, oversheath; Tegillum parcel fibre core in said; Tegillum in the said oversheath parcel.
Preferably, said coaxial cable has 3, roughly is the isosceles triangle setting; Be provided with novel optical cable in the space between the said adjacent coaxial cable.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Composite cable in the flat type elevator cable of new composite optical cable of the present invention; With novel optical cable and coaxial cable is compound and space between adjacent coaxial cable in; Need not inner separately core is strengthened; The external diameter of composite cable of the present invention is little, production process is simple, and cost is low; Production cost of the present invention is low, the life-span is long.

Embodiment
Be depicted as the flat type elevator cable of a kind of new composite optical cable of the present invention like accompanying drawing 2,3, comprise composite cable 11, common cable 12, flat sheath 13; Said composite cable 11, common cable 12 have many respectively, are arranged on straight line regularly, by flat sheath 13 parcels; Said composite cable 11 comprises coaxial cable 2, sheath 9; Said coaxial cable 2 has 3, roughly is the isosceles triangle setting; Be provided with novel optical cable 5 in the space between the said adjacent coaxial cable 2; Said sheath 9 wraps all coaxial cables 2, novel optical cable 5; Said coaxial cable 2 comprises core conductor 3, core insulator 4; Said core insulator 4 parcel core conductors 3; Said novel optical cable 5 comprises fibre core 6, interior tegillum 7, oversheath 8; Tegillum 7 parcel fibre cores 6 in said; Tegillum 7 in said oversheath 8 parcels.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Composite cable in the flat type elevator cable of new composite optical cable of the present invention; With novel optical cable and coaxial cable is compound and space between adjacent coaxial cable in; Need not inner separately core is strengthened; The external diameter of composite cable of the present invention is little, production process is simple, and cost is low; Production cost of the present invention is low, the life-span is long.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
